Cubic crystal system - Wikipedia
网页In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals. There are three main varieties of these crystals: Primitive cubic (abbreviated cP and alternatively called simple cubic)

网页2022年8月28日 · The diamond cubic structure consists of two interpenetrating face-centered cubic lattices, with one offset 1/4 of a cube along the cube diagonal. It may also be described as face centered cubic lattice in which half of the tetrahedral sites are filled while all the octahedral sites remain vacant.

10.7: Lattice Structures in Crystalline Solids
网页2022年10月27日 · This structure is also called cubic closest packing (CCP). In CCP , there are three repeating layers of hexagonally arranged atoms. Each atom contacts six atoms in its own layer, three in the layer above, and three in the layer below.
Common Cubic Structures | Cambridge Centre for Gallium Nitride
网页The three main common representatives are: the simple cubic structure (sc) (also known as primitive cubic) the body-centred cubic structure (bcc) the face-centred cubic structure (fcc) In the following sections you can learn more about these structures and make you own 3D paper models.
Face-Centered Cubic (FCC) Unit Cell - Materials Science
网页2022年11月24日 · The crystal structure is based on the Bravais lattice of the same name, with a single atom at each lattice point on the cube’s corners and faces. FCC is one of the most stable crystal structures and has the highest packing density. In some textbooks, FCC may also be abbreviated as CCP, which stands for Cubic Close-Packed.
